“…Una alternativa para enfrentar dicho problema es el uso de sistemas que proveen la estimación de las señales de difícil manipulación desde la perspectiva algebraica, tales como los observadores proporcional integral generalizados (GPI). Las características y aplicaciones de este tipo de observadores han sido documentadas en múltiples trabajos que abordan problemas como el control de señales periódicas (Cortés-Romero, et al, 2014), control de convertidores electrónicos de potencia (Zurita-Bustamante et al, 2011), sincronización de circuitos caóticos (Luviano-Juarez et al, 2010), control de máquinas eléctricas (Sira-Ramírez et al, 2014b) y aplicaciones de tolerancia a fallos (Cortés-Romero et al, 2013), entre otros.…”

Este artículo propone una alternativa para la estimación de parámetros de un helicóptero de dos grados de libertad que opera bajo control de lazo cerrado. Como principal contribución se plantea una variante de la metodología algebraica de identificación, la cual involucra el uso de observadores proporcional integral generalizados (GPI). Estos observadores están encargados de proveer la estimación de las derivadas de las salidas del sistema para su computo directo en los casos donde existen operaciones no lineales de difícil manipulación analítica. Inicialmente, se establece un identificador algebraico para cada ecuación no-lineal del sistema a fin de estimar los parámetros de interés. Posteriormente, para la selección de los parámetros estimados se adopta el criterio de la integral del cuadrado del error y el correspondiente índice de error. Finalmente, se presentan resultados experimentales que permiten validar la estrategia de identificación utilizada y los parámetros estimados con respecto al modelo asumido.

“…Additionally it was considered that the total disturbances can be approximated by m − 1 finite order polynomials. Based on this assumption observers with m extended states were proposed as this was the approach used in the GPI control concept [12].…”

An Active Disturbance Rejection Control based on Generalized Proportional Integral observer (ADRC with GPI observer) was developed to control the gait of a bipedal robot with five degrees of freedom. The bipedal robot used is a passive point feet which produces an underactuated dynamic walking. A virtual holonomic constraint is imposed to generate online smooth trajectories which were used as references of the control system. The proposed control strategy is tested through numerical simulation on a task of forward walking with the robot exposed to external disturbances. The performance of ADRC with GPI observer strategy is compared with a feedback linearization with proportional-derivative control. A stability test consisting on analyzing the existence of limit cycles using the Poincaré's method revealed that asymptotically stable walking was achieved. The proposed control strategy effectively rejects the external disturbances and keeps the robot in a stable dynamic walking.
